VENTS VUT 800 WH-4

Description

DESCRIPTION

The VUT WH air handling units with a water heater are used in ventilation and air conditioning systems in commercial, office and other public or industrial premises that require an economical solution and a controlled ventilation system.

CASING

The casing is made of aluzinc steel with 25 mm thick mineral wool heat- and sound-insulating layer.

FILTER

FANS

The units are equipped with supply and exhaust centrifugal double-inlet fans with forward curved blades and built-in thermostat with automatic restart.

HEAT EXCHANGER

HEATER

The water heater.
The water heaters are designed for max. operating pressure 1.0 MPa (10 bar) and max. heat medium operating temperature 95 °C.

AUTOMATION AND CONTROL SYSTEM

The unit incorporates an integrated automation and control system with a multi-functional control panel with LCD display.
The standard delivery set includes 10 m connection cable for connection to the remote control panel.

CONTROL AND PROTECTION FUNCTIONS

Control from the control panel: switching on/off, threespeed fan selection, selecting heating/cooling modes (if connected to duct heater); room temperature display.
Maintaining supply air temperature set from the control panel by controlling the circulation pump and actuating the heat medium regulating valve; input from the heat medium flow switch (pump alarm).
Safe start-up/ shutdown of the fans, warming up of the water heater before start-up; return heat medium temperature control when the fan is off.
Freezing protection of the water heating coils by the exhaust temperature sensor and the return heat medium temperature sensor.
Control of the compressor and condensing unit of the water cooler by the room temperature sensor (for the models equipped with a duct air cooler).
Actuating the external air dampers with a return spring.
Unit operation according to week schedule (set at the system setup).
Unit shut down at signal from the fire alarm system.
Smooth bypass damper control in the bypassing mode to prevent the heat exchanger freezing.

MOUNTING

The unit is designed for indoor mounting.
While mounting the unit provide the correct condensate collection and drainage.
Access for the unit servicing and filter cleaning is from the side panels on the left from supply air side.
